Question

A ball of mass 0.800 kg is carefully balanced on a shelf that is 3.00 m above the ground. What is its gravitational potential energy?a. 2.08J b. 20.4J c. 7.84J d. 25.5J

Answer 1

G=mgh
G=0.8x3/10
G=0.24

Answer 2

Potential energy is the mechanical energy associated with the location of a body within a force field (gravitational, electrostatic, etc.) or the existence of a force field inside a body (elastic energy)

The gravitational potential force is subject to the relationship

`PE = mgh`

Where,

m = mass

g = Gravitational Energy

h = Height

If our height is 3 meters, the mass is 0.8Kg and the earth has a gravitational acceleration of 9.8m / s, we will have to

PE = (9.8)(3)(0.8)

PE = 23.52J

The closest answer is D.
